ENKING APPARATUS FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 652,343, dated June 26, 1900. Application filed May 9, 1898. Renewed December 18, 1899. Serial No. 740,825. (No model.)

To (Z5 whom it may concern:

Be it known that I, THEODORE BRIEGEL, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Inking Apparatus for Printing-Presses and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to inking apparatus for printing-presses embodying a reciprocating ink-table and distributing-roller. Distributing-rollers, generally speaking, are rotated back and forth by a reciprocating inking-table contacting therewith. They are revolved in opposite directions at high speed, and when the table passes from contact said rollers continue to rotate by their momentum until said table again coming in contact reverses them. Said rollers are necessarily made of a soft composition, and the reciproeating table striking them in reverse to motion last imparted wears the composition rapidly and often tears it.

My invention consists of a simple and economical mechanism adapted to be attached to a variety of printing-presses having inkdistributing rollers, whereby the motion of said rollers is instantly checked when the inktable passes from contact and are then given a reverse motion coinciding with the return motion of said table preparatory to their succeeding contact therewith.

My invention further consists in novel means for alternately lowering and lifting the iron rollers or riders to and from contact with the distributing-rollers.

In theaccompanying drawingsI have shown my invention applied to a Campbell improved two-revolution book-press having four distributing-rollers with superincumbent riders or iron rollers, it being understood that my invention can be applied with the proper number of contact-points or bearing-surfaces for the shafts of composition and iron rollers to operate any number of rollers used by different presses. While the drawings show the riders or iron rollers in place, it will be seen that the mechanism for controlling the dis tributing-rollers operates independently of the riders, which may therefore be removed, if desired, without affecting the control of the composition rollers.

Referring more particularly to the drawings, Figure 1 is a side elevation showing my mechanism in position and parts of the frame of a press adjacent thereto, and Fig. 2 is a top plan view of the same. Fig. 3 is a transverse section taken on line 3 3 of Fig. 1. Figs. 4 and 5 are detail views of swing-levers. Fig. 6 is an edge view of supporting-bracket 11. Fig. 7 is a detail view of the stud 23. Fig. 8 is a detail view of the screw-stud 27. Fig. 9 is an edge View of arm 16. Fig. 10 is a detail view showing arm 19, with rollers and retaining-screw assembled. Figs. 11 and 12 are top and edge views, respectively, of bearing 28. Fig. 13 is a detail View of the yielding hinge-bearing connecting the jaws of the friction-clutch to the swing-levers.

26, secured to the lower end of lever 14.

28 denotes bearings provided with flanges friction-clutch, as shown in Figs. 2 and 3, (Figs. 11 and 12 showing bearings detached.)

Said bearings act as independent supports to the 'endsof shafts opposite to those upon which jaws 3 and 5 operate.

As rollers 9 are not used at all times in printing, it is evident they may be removed,

' and their absence will not interfere with the operation of my mechanism for controlling the composition or distributing rollers 10. When rollers 9 are not in use, the bearings 28 are removed. The rollers 10 may be easily removed for cleaning, &c., by lifting the ends opposite to those engaged by the jaws 3 and 5 and then pulling said engaged ends from between the jaws. As usual, the iron rollers ride upon the distributing-rollers, their entire weight resting upon the surface of the same, except as hereinafter mentioned.

My invention operates as follows: As shown in Fig. 1, the iron rollers bear upon the distributing-rollers and the inking-table has passed from underneath the latter, but is still 1 in contact with wheel 25 on arm 18. Now as the inking-table passes from contact with said wheel, releasing arm 18, the spring 21 draws upon the. lower end of lever 14, rocks shaft 22., and moves jaw 5 backward and jaw 3 forward. As jaw 5 moves back, the ends of shafts of rollers 9 will ascend the incline 7, tilting them in the position shown in dotted lines. 1

(See Fig. 3.) In this positionfthe opposite ends of shafts of said rollers will rest on the bearings 28, and thus clear said rollers of the distributing-rollers. In this position the iron rollers or riders are supported by the jaw 5 at one end andthe bearings 28 at the other, and simultaneously jaws 3 and 5 will clamp firmly the ends of shafts of rollers 10 through the action of compression-springs 20. It will be seen that the momentum of the rollers 10 when said jaws come in contact with their shaft ends aid spring 21 to draw said jaws into a clamping position against the resiliency of compression-springs 20. It is also evident that the momentum of rollers 9 will carry their shaft ends up the inclines 7 with The jaws being now clamped upon shaft ends 10, as the inking-table again comes in contact with roller 25 it gives a quick parallel move- 1 ment to jaws 3 and 5 in directions opposite one to the other, which movements give rollers 10 an initial rotary motion to coincide with the reverse movement of the inking-table before it strikes them. The shaft ends of rollers 9, moving down the inclined plane, bring It is evident that this return movement of the inking-table as it strikes wheel 25 raises arm 19 21 denotes a coiled spring attached at one end to frame 1 and at the other end to stud and causes friction-wheel 25 to hear back upon arm 16, which through arm 17 pulls back the upper end of the spring-lever14, thus expanding spring 21 preparatory to its succeed and adapted to be placed between ends of the shafts of distributing and iron rollers orridi ersupon the side of the press opposite to the f Letters Patent, is
